Is your Gmail account nearly full? If it is you can either purchase more space or go through and individually delete every cat picture attachment. Alternately, you can use a clever Google Docs trick shared by tech blog Digital Inspiration to sort your Gmail messages by size and quickly delete space-hogging junk.

We've covered webapps that do this before, but if you're uncomfortable granting access to a third party this method keeps everything within the Google ecosystem. It's a pretty simple four-step process that first links Google Docs and your Gmail together. Once that's granted it then creates a spreadsheet of all your big messages. When it's done you can sort by size and start cleaning out those data hogs with a couple clicks, no third party authorization required. Hit up the Digital Inspiration for a sample spreadsheet and full guide to running through this for yourself.
